To -'aZZ whom it may concern:

Be it known that I, FRANK M. WA'rnns, a citizen of the United States,residing at Springfield, in the county Ohio, have invented a new anduseful Mechanical Movement, of which the following is a specification.

ot larger diameter than itsel gear in turn meshes into a My inventionrelates to an improvement in that class of devices for eonvertinga slowrotary movement into a fast one or a fast rotary movement into a slowone with the aid of but one shaft or stud in connection with the gearingby which this result is accomplished.

It consists of a webbed internally-geared in the center bored to receivethe shaft, which rotates freely in it. Upon the shaft is keyed orotherwise fastened a spur-gear having a pitch-diameter something lessthan the pitch-diameter of the internal gear, and when in properposition resting upon or against the web of the internal gear, thusbringing the sides of both upon or nearly so the same line, and leavinga space between the faces of the two gears snfficient to admit a coggedspur-pinion having the same pitch of teeth as the annular and spur gear,and properly meshing into both at the same time. Thespur-pinion is partof aspur-gear f, to which it is fastened on the side, or may moreproperly form part of the same casting, and this spursmaller gear orwhich is bored through its center to allow it to run freely upon theshaft, and may be part of or connected to either a with eccentric, crankwith crank-pin, pulley, spur, annular or bevel gearing for transmittingmotion to other mechanism. The internally-geared wheel may, and in thiscase does, form part of a casing in which the gearing is protected fromdirt or other foreign substances which might interfere with its properworking, the other part of the casing being bolted or otherwise fastenedto it sufficiently close to allow the free movement of the combined gearand pinion, and to prevent at the same time any tendency to dip orrotate in any direction other than that desired, and in which it isfurther assisted by having upon the side of the shaft-pinion a flange orextension of the casting above the tops of the pinion,

cogs. While this movement may be accomplished by using only oneintcrmeshing combined spur and pinion, the result will be the same ittwo or more are used at the same time, with the advantage of equalizingthe pressure of the pinion upon the shaft on all sides. It will nowreadily be seen that by turning the shaft upon which the spur-gear isfastened, and allowing the annular gear to remain fixed, the combinedspur-gear and pinion will revolve upon its own axis and at the same timemove in. a circle around the shaft. The advantages derived by allowingthe pinion of the combined or double gear to run free between theannular and spur, instead of upon a stud or shaft, are, to lubricate atthat point, and the required motion gotten with less cost and fewerpieces in building it.

To better ill is had to th Whi011- Figure 1 is a cross-section with thecasing partly removed, in which.

The mechanism may ustrate my invention, reference e accompanyingdrawings, in

be employed to produce anyrapid or slow movement, and maybe operated bymanual or other power. Numerous obvious applications of the device maybe it requires no oil made-such as to mowing and reaping ma- 1 ing intopinion a, with casing A and B, hav- :0 chines, lawn-mowers, andhorsc-powers ing' projections E, as shown. Where an accelerated motionis required, and In testimony of which I hereunto set my intraction-engines, hoisting machinery, &c., hand. where a slow motion isneeded.
